- W2387756814 abstract "Aiming at the difficulties of the poor universality and the precipitation of detection performance at low SNR in the field of voice activity detection,this paper proposes a new voice activity detection method in high intensity noise (stationary noise and non-stationary noise) environments based on modified entropy-energy and time-frequency enhancement. First of all,it estimates the environment noise and enhances the speech signal in frequency-domain and time-domain. Secondly,a good robust feature parameter is employed to detect the speech endpoint. The experimentation result indicates that the algorithm has a better detection performance in stationary noise and non-stationary noise environments and a good universality." @default.
